To all whom it maf/1 conocen Be 1t known that l', VTILLIAM .Monson WHITE, s citizen 'of the -United States, resld- 'ing at Milwaukee, in the county of Milf.

W'uukee and State of 'Vlisconsin. have in vented u certain new und useful Improve# ment in Centrifugal Pumps, oi Which-the following is a specification.

This invention relates to improvements in thev construction of centrifugal pumps, blowers, or similar devices, and particularly to improvements in the constructionoi the cesings und supporting frames for such den n'object of the invention is-to provide an inclosing casing :tn d supporting frames for contriugal pumps und like apparatus, which is simple in construction and in which the number of different ports comprising the structure is reduced to e minimum.

Another object is to Arovide` uv pump casthe parts muy be resdily interclisnged with others."

Still enotherobject is to provide e, pump casing in which ythe direction of the inlet .and discharge passages leading to the pump casing may be readily varied to suit different' conditions.

A .further object o the invention is to rovide u simple and effective supporting .'raine for the pump cusings and the'besr-- .ings in which 'the roturypurnp'elements are mounted, 'whereby the hearings may he confstently maintained in a. vfined position irrespeptiye of theedjusted positions of the cesings.

`particular object is to provide an upper rio connecting each bearing tothe spiral easing. f

The centrifugal pump consistsessentially 'of .n spirali pump casing l having suction passages 7 leading thereto and e discharge passage 6 leading therefrom, and lmvings pump rotor 8 rotatable therein.` The4 suction inlet passages? are -formed inthe inten` changeable suction heads 2 which connect With the suction openings leadingv to the rotor 8 through passages formed in the end covers 10, rThe interchangeable spider supporting' frames 3 each consist of o circuler flange 90 connected with a bearing housing 4 by means of a plurality of spaced ribs and supported upon suitable frame supporting Patented Apr. 6,1915@ l Application mea may 1, 191eA serialize. 765,401..v I

feetpr pads 1S. The pumpshaft 5 which carries the pump rotor or runner 8, is mounted in bushing bearings 1l secured Within the bearing housmgsfal by meansof 'locking screws 15. lling oilers 13 which are admitted to the bearing housings si through.

openings which are normally inclosed by means of 'bearing cups 16, serve to provlde sulilicient lubrication to the vbemrings 14. The shaft 5 passes 'directly through the Asuction' inlet casings '2, the joints 'between the shaft 5 and the cesingsfQ-'being 'packed by means of suitable stuing .boxes i2.

The suction pipes 1 7 ,connect with the suction inlet pessuges 7 of the suction .heads 2, and serve to `admit the vfluidv to the pump runner 8 from 'the supply souree.- The discharge pipe 19 connects directly with the pump dischorgepassage 6 of the casing' l.4

The cusingl, end covers l0, und supporting fran'ies nre united by means of circular series oi' equally. spaced' studs 9 which are secured to the circuler lugs ll of the casing l' andV have outer ends extending through registering openings in the end covers l0 and circular ilnngesSO of the supportingV frames 3. The studs 9,it is evident', are not essentially such, 'es bolts muy be readily used as an elternative'means of uniting the velements Without involving additional invention. The surfaces ocoaction ofthe casing, 1, end coversl() and frames 3 with 'each other are plane surfaces perpendicular to the anis-.of the shaft 5.' I

The casing 1 is formed symmetrical about l a plane passing through the coutwsetliereof end. perpendicular to the axis of the-shaft 5. I .The end covers l0 and s'i'iction chambers 2 which are formed in one therewith, emetofthe inlet pipesy i7 and discharge pipe 19 plishgjq'l by removing the clamping nuts from in various directions, without changing the position of the bearing casings l. Angular adjustment of the. casing l may be accomy the studs?) and shifting the end covers 10 me spider supliorting spider frames 3 along the shaft 5 and 4away from the casing l until the studs 9 are withdrawn from the openings in the end covers 10 and frames 3, after which the casing may be shifted to the desired angular position and the elements reassembled. lf it is desired to adjust the end covers 10 through angles which are greater-than the spacing'of the adjacent spider ribs of the -franies 8 'will permit, it is necessary to remove the end covers l0 and suction heads 2 from Within the frames 3 and t0 reassemble the elements so that the desired angular positions may be attained.

ln the form of spider supporting frame disclosed in Fig. 3, the fra-mo is formed of tivo portions, namely, an upper portion 23 and a lower portion 2. These i'rame portions 23, 2G, have semi-cicular ange portions 27, 30, which with the frame port-ions 23, 9,6, assembled, are secured to each other by means of bolts 28 or other suitable clampingdevices. The bearing housing cap 24T is formed in one with the upper frame portion 23 and with the frame portions 23, 26, assembled, is clamped to the lower bearing portion 31 by means o bolt-s 25 or other suitable clamping means. `portion 2G is provided 'Withsuitable supporting 'Feet or pads 29.' The application of 'the modified form oi3 supporting frame to an assembled -pump is analogous to that 'of frames 3, as"clis closed in Figs. l. and 2. The angular adjustments ci the respective elements with the use of the modified traine, are also attained in the manner above explained.

llt will be noted that by making the various parts on either side of the purnpA interchangeable, the number oie stock parts required bv*manufacturers of these pumps is reduced toa minimum. since the number et dillerent partncomprising a complete pump housing aud'supporting frame is onlj-r three, these laugtl're casing l. the end covers l0,

and the spider supporting trames 3. The sfu'rlr spas' .fi the clamping devices or' sides et 'the casing l, andl "oi'mation or' this casing.y reversal cas and e messes also permits angular listing ot the cas 65 'parts required to make up the frame and lalso requires additional machining oi the parts along the frame parting surfaces.

It should be understood that it is not de-iv sired' to be limited to the exact details of construction shov'vn and described, for obvious inodiiications will occur to a person skilled in the art.
